Definitions

  • the present invention relates to a composite component and a method for producing a composite component with a first component element and a second component element, wherein the first component element and the second
  • the composite component are connected together by an adhesive bond.
  • the composite component may be a supporting part of a motor vehicle body.
  • a structural element i. a reinforcing element to be arranged in a region between an outer shell and an inner shell, in particular in a shell-type motor vehicle body.
  • the structural element may consist of a fiber-reinforced plastic, such as carbon fiber reinforced plastic, while the inner and / or outer shell may consist of a steel.
  • the structural element is connected by means of a bonding adhesive by a surface connection with the outer and / or inner shell.
  • the adhesive cavity forms a localized splice or
  • Adhesive joint which is an adhesive bond between the first
  • Part element and the second component element forms. After its expansion, the thermally active plastic forms a wall which extends in the gap between the first component element and the second component element.
  • the gap is a gap between the first component element and the second component element.
  • Composite component can be formed.
  • the first component element and the second component element can be simply connected to a previously defined local point with an adhesive connection.
  • this method allows to create localized adhesive joints.
  • adhesive is only on locally limited locations, ie applied to local splices. So it does not have the entire gap between the first component element and the second
  • the present method enables the second component member to be pre-fixed to the first member member by expanding the thermally active resin.
  • This has the advantage that the first component element can pass through further processes with the second component element until the actual adhesive connection for connecting the second component element to the first component element is produced.
  • This is particularly advantageous if the first component element and the second component element have to pass through process steps in common anyway, which require heating of the first component element together with the second component element.
  • such a heating of the second component element with the first component element with finished adhesive bond would be disadvantageous because an adhesive bond is thermally stable only within certain limits.
  • the first component element is formed from a first material and the second component element is formed from a second material.

Description

Verbundbauteil und Verfahren zum Herstellen eines Verbundbauteils  Composite component and method for producing a composite component
Die vorliegende Erfindung bezieht sich auf ein Verbundbauteil und ein Verfahren zum Herstellen eines Verbundbauteils mit einem ersten Bauteilelement und einem zweiten Bauteilelement, wobei das erste Bauteilelement und das zweite The present invention relates to a composite component and a method for producing a composite component with a first component element and a second component element, wherein the first component element and the second

Das Strukturelement kann dabei aus einem faserverstärkten Kunststoff, wie beispielsweise kohlefaserverstärkten Kunststoff, bestehen, während die Innen- und/oder Außenschale aus einem Stahl bestehen kann. Das Strukturelement wird dabei mittels eines Verbindungsklebers durch eine flächige Verbindung mit der Außen- und/oder Innenschale verbunden. Ein derartiges Bauteil in Schalenbauweise mit einem Strukturelement ist in der DE 102007010341 A1 beschrieben. It is known a structural element, i. a reinforcing element to be arranged in a region between an outer shell and an inner shell, in particular in a shell-type motor vehicle body. The structural element may consist of a fiber-reinforced plastic, such as carbon fiber reinforced plastic, while the inner and / or outer shell may consist of a steel. The structural element is connected by means of a bonding adhesive by a surface connection with the outer and / or inner shell. Such a component in shell construction with a structural element is described in DE 102007010341 A1.
Es ist nunmehr die Aufgabe der vorliegenden Erfindung ein Verbundbauteil und ein Verfahren zum Herstellen eines Verbundbauteils mit einem ersten Bauteilelement und einem zweiten Bauteilelement, die durch eine Klebeverbindung miteinander verbunden sind, zu schaffen, das eine einfache Ausbildung von lokal begrenzten Klebestellen ermöglicht. It is now the object of the present invention to provide a composite component and a method for producing a composite component with a first component element and a second component element, which are interconnected by an adhesive connection, which allows a simple formation of localized splices.
Diese Aufgabe wird durch ein Verfahren gelöst, das die Merkmale und Schritte von Patentanspruch 1 aufweist. Gemäß der vorliegenden Erfindungen hat das Verfahren zum Herstellen eines Verbundbauteils mit einem ersten Bauteilelement und einem zweiten This object is achieved by a method having the features and steps of claim 1. According to the present invention, the method for producing a composite component with a first component element and a second
Bauteilelement, die durch eine Klebeverbindung miteinander verbunden sind, den Schritt Component element, which are interconnected by an adhesive connection, the step
Ausbilden eines Klebehohlraums mit folgenden Unterschritten:  Formation of an adhesive cavity with the following substeps:
Aufbringen von thermisch aktiven Kunststoff auf eine  Applying thermally active plastic to a
Klebeverbindungsseite des ersten Bauteilelements oder/und auf eine Klebeverbindungsseite des zweiten Bauteilelements,  Adhesive bonding side of the first component element and / or on an adhesive bonding side of the second component element,
Anordnen des ersten Bauteilelements an dem zweiten Bauteilelement, wobei ein Spalt zwischen der Klebeverbindungsseite des ersten Bauteilelements und der Klebeverbindungsseite des zweiten Bauteilelements ausgebildet ist, und  Arranging the first component element on the second component element, wherein a gap is formed between the adhesive connection side of the first component element and the adhesive connection side of the second component element, and
Zuführen von Wärme auf eine Art und Weise, dass sich der thermisch aktive Kunststoff ausdehnt und eine Abgrenzung in dem Spalt zwischen dem ersten Bauteilelement und dem zweiten bildet, und Ferner hat das Verfahren den Schritt:  Supplying heat in such a way that the thermally active plastic expands and forms a boundary in the gap between the first component element and the second, and further the method comprises the step:
Füllen des ausgebildeten Klebehohlraums mit Klebemittel zum dauerhaften Verbinden des ersten Bauteilelements mit dem zweiten Bauteilelement.  Filling the formed adhesive cavity with adhesive for permanently connecting the first component element to the second component element.
Der Klebehohlraum bildet eine lokal begrenzte Klebestelle bzw. The adhesive cavity forms a localized splice or
Klebeverbindungsstelle, die eine Klebeverbindung zwischen dem ersten Adhesive joint, which is an adhesive bond between the first
Bauteilelement und dem zweiten Bauteilelement bildet. Der thermisch aktive Kunststoff bildet nach seiner Ausdehnung eine Wand, die sich in dem Spalt zwischen dem ersten Bauteilelement und dem zweiten Bauteilelement erstreckt. Der Spalt ist ein Zwischenraum zwischen dem ersten Bauteilelement und dem zweiten Bauteilelement. Part element and the second component element forms. After its expansion, the thermally active plastic forms a wall which extends in the gap between the first component element and the second component element. The gap is a gap between the first component element and the second component element.
Es können auch mehrere Klebehohlräume und damit Klebestellen in dem It can also be several adhesive cavities and thus splices in the
Verbundbauteil ausgebildet werden. Composite component can be formed.
Durch das erfindungsgemäße Verfahren können das ersten Bauteilelement und das zweite Bauteilelement an einer zuvor definierten lokalen Stelle einfach mit einer Klebeverbindung verbunden werden. Zudem ermöglicht dieses Verfahren lokal begrenzte Klebeverbindungen zu schaffen. Damit wird Klebemittel lediglich an lokal begrenzten Stellen, d.h. an lokalen Klebestellen, aufgebracht. Es muss also nicht der gesamte Spalt zwischen dem ersten Bauteilelement und dem zweiten By virtue of the method according to the invention, the first component element and the second component element can be simply connected to a previously defined local point with an adhesive connection. In addition, this method allows to create localized adhesive joints. Thus, adhesive is only on locally limited locations, ie applied to local splices. So it does not have the entire gap between the first component element and the second
Bauteilelement mit Klebemittel gefüllt werden. Dies spart Material, Gewicht und Kosten. Außerdem ermöglicht das vorliegende Verfahren durch die Zuführung von Wärme, dass das zweite Bauteilelement an dem ersten Bauteilelement durch Ausdehnung des thermisch aktiven Kunststoffs vorfixiert wird. Dies hat den Vorteil, dass erste Bauteilelement mit dem zweiten Bauteilelement noch weitere Prozesse durchlaufen kann, bis die eigentliche Klebeverbindung zum Verbinden des zweiten Bauteilelements mit dem ersten Bauteilelement hergestellt wird. Besonders vorteilhaft ist dies, wenn das erste Bauteilelement und das zweite Bauteilelement gemeinsam sowieso Prozessschritte durchlaufen müssen, die eine Erwärmung des ersten Bauteilelements zusammen mit dem zweiten Bauteilelement erfordern. Eine derartige Erwärmung des zweiten Bauteilelements mit dem ersten Bauteilelement mit fertig ausgebildeter Klebeverbindung wäre jedoch unvorteilhaft, da eine Klebeverbindung nur in bestimmten Grenzen wärmestabil ist. Component element filled with adhesive. This saves material, weight and costs. Moreover, by applying heat, the present method enables the second component member to be pre-fixed to the first member member by expanding the thermally active resin. This has the advantage that the first component element can pass through further processes with the second component element until the actual adhesive connection for connecting the second component element to the first component element is produced. This is particularly advantageous if the first component element and the second component element have to pass through process steps in common anyway, which require heating of the first component element together with the second component element. However, such a heating of the second component element with the first component element with finished adhesive bond would be disadvantageous because an adhesive bond is thermally stable only within certain limits.
Bevorzugt ist bei dem erfindungsgemäßen Verfahren das erste Bauteilelement aus einem ersten Werkstoff gebildet und das zweite Bauteilelement ist aus einem zweiten Werkstoff gebildet. Der erste Werkstoff und der zweite Werkstoff sind unterschiedliche Werkstoffe.

The first material and the second material are different materials.
Insbesondere weisen der erste Werkstoff und der zweite Werkstoff unterschiedliche thermische Längenausdehnungskoeffizienten auf. In particular, the first material and the second material have different thermal expansion coefficients.
Bei zwei Werkstoffen mit unterschiedlichen Längenausdehnungskoeffizienten ist es besonders vorteilhaft, eine Klebeverbindung zu schaffen, die elastischer ist als eine Verbindung mit mechanischen, formschlüssigen Verbindungsmitteln wie Bolzen, beispielsweise Schrauben oder Nieten. For two materials with different coefficients of linear expansion, it is particularly advantageous to provide an adhesive bond that is more elastic than a connection with mechanical, positive connection means such as bolts, such as screws or rivets.
Besonders bevorzugt ist der erste Werkstoff aus einem Kunststoff ausgebildet, wobei der zweite Werkstoff aus einem metallischen Werkstoff ausgebildet ist. Bei dieser Werkstoffpaarung ergibt sich in vielen Fällen das Problem unterschiedlicher Längenausdehnungskoeffizienten, das jedoch mit der vorliegenden Erfindung angemessen gelöst werden kann. Selbstverständlich sind auch andere Werkstoffpaarungen, die aus dem ersten Werkstoff und dem zweiten Werkstoff gebildet sind, möglich. Z.B. kann das erste Bauteilelement aus Stahl, Aluminium oder Kunststoff, z.B. faserverstärktem Particularly preferably, the first material is formed from a plastic, wherein the second material is formed from a metallic material. In many cases, this pairing of materials gives rise to the problem of different coefficients of linear expansion, which, however, can be adequately solved with the present invention.

For example, the first component element made of steel, aluminum or plastic, eg fiber-reinforced
Kunststoff, bestehen. Das zweite Bauteilelement kann wiederum aus Aluminium, Kunststoff, z.B. faserverstärktem Kunstsoff, Stahl oder Magnesium bestehen. Plastic, consist. The second component element may in turn be made of aluminum, plastic, e.g. fiber reinforced Kunstsoff, steel or magnesium.
Bevorzugt wird ferner der thermisch aktive Kunststoff derart aufgebracht, dass der thermisch aktive Kunststoff zumindest nach dem Schritt Zuführen von Wärme, bei dem sich der thermisch aktive Kunststoff ausdehnt, eine geschlossene Abgrenzung in dem Spalt bildet. Preferably, the thermally active plastic is further applied such that the thermally active plastic, at least after the step of supplying heat at which the thermally active plastic expands, forms a closed boundary in the gap.
Der thermisch aktive Kunststoff kann damit mit Unterbrechungen aufgebracht werden, wobei diese Unterbrechungen durch die Ausdehnung des thermisch aktiven Kunststoffes bei der Zuführung von Wärme geschlossen werden und damit eine geschlossene Raupe bilden. The thermally active plastic can thus be applied with interruptions, these interruptions are closed by the expansion of the thermally active plastic in the supply of heat and thus form a closed bead.
Alternativ kann der thermisch aktive Kunststoff bereits beim Aufbringen in Form einer geschlossenen Raupe, die die Abgrenzung bildet, ausgebildet werden. Alternatively, the thermally active plastic can be formed already during application in the form of a closed bead, which forms the boundary.

According to the present invention, further, in the step of supplying heat, process heat is supplied in a coating step of the composite component.
Insbesondere ist die Wärme Prozesswärme, die zum Trocknen der Beschichtung notwendig ist, und die für das Zuführen von Wärme, um den thermisch aktiven Kunststoff zu aktivieren, zusätzlich genutzt wird. In particular, the heat is process heat, which is necessary for drying the coating, and which is additionally used for the supply of heat in order to activate the thermally active plastic.
Somit kann einerseits die Prozesswärme zur Vorfixierung des zweiten Thus, on the one hand, the process heat for prefixing the second
Bauteilelements an dem ersten Bauteilelement genutzt werden und andererseits kann das Füllen des Klebehohlraums mit Klebemittel nach dem Zuführen von Prozesswärme durchgeführt werden, so dass die Prozesswärme zum Trocknen der Beschichtung hinsichtlich der Klebeverbindung keine nachteilige Wirkung hat. Bevorzugt wird die Beschichtung in einem Tauchverfahren auf das Verbundbauteil aufgebracht. Es sind jedoch auch andere Beschichtungsverfahren im Component can be used on the first component element and on the other hand, the filling of the adhesive cavity with adhesive can be carried out after supplying process heat, so that the process heat for drying the coating with respect to the adhesive bond has no adverse effect. The coating is preferably applied to the composite component in a dipping process. However, there are other coating methods in the

Bevorzugt ist das erste Bauteilelement ein Hohlprofil und das zweite Bauteilelement ein Verstärkungselement, das innerhalb des Hohlprofils angeordnet ist, wobei bei dem Schritte Ausbilden des Klebehohlraums der thermisch aktive Kunststoff auf eine Außenseite des Verstärkungselements oder/und auf eine Innenseite des Hohlprofils aufgebracht wird. Preferably, the first component element is a hollow profile and the second component element is a reinforcing element which is arranged within the hollow profile, wherein in the steps of forming the adhesive cavity, the thermally active plastic is applied to an outer side of the reinforcing element and / or on an inner side of the hollow profile.
Das Hohlprofil kann ferner aus einem ersten Hohlprofilbauteil und einem zweiten Hohlprofilbauteil bestehen. The hollow profile may further consist of a first hollow profile component and a second hollow profile component.
Dies erleichtert ein Einbringen des Verstärkungselements in das Hohlprofil. Z.B. kann das Verstärkungselement zunächst in das erste Hohlprofilbauteil eingelegt werden und danach das zweite Hohlprofilbauteil an das erste Hohlprofilbauteil angefügt werden. This facilitates introduction of the reinforcing element into the hollow profile. For example, For example, the reinforcing element can first be inserted into the first hollow profile component and then the second hollow profile component can be attached to the first hollow profile component.
Das Hohlprofil kann auch aus mehr als zwei Hohlprofilbauteilen bestehen. The hollow profile may also consist of more than two hollow profile components.

Between the hollow section 3 and the reinforcing element 5 is the
Klebehohlraum 7 ausgebildet. Der Klebehohlraum 7 befindet sich in dem Spalt 9, der zwischen dem Hohlprofil 3 und dem Verstärkungselement 5 ausgebildet ist. Der Klebehohlraum 7 ist durch das Hohlprofil 3, das Verstärkungselement 5, einen ersten Ring 13 und einen zweiten Ring 14 aus thermisch aktiviertem Kunststoff 11 begrenzt. Der thermisch aktivierte Kunststoff 11 besteht aus aufgeschäumtem Kunststoff, der eine Breite des Spalts 9, d.h. einen Abstand zwischen dem Hohlprofil 3 und dem Verstärkungselement 5, vollständig ausfüllt. In den Klebehohlraum 7 ist Klebemittel eingespritzt, wobei das Klebemittel in Fig. 1 nicht dargestellt ist. Als thermisch aktiver Kunststoff 11 ist im vorliegenden Ausführungsbeispiel ein dauerelastischer Schaum aus Ethylen-Vinylacetat oder Ethylen-Butylacrylat verwendet. Es kann aber auch anderer geeigneter thermisch aktiver Kunststoff verwendet sein. Adhesive cavity 7 is formed. The adhesive cavity 7 is located in the gap 9 which is formed between the hollow profile 3 and the reinforcing element 5. The adhesive cavity 7 is bounded by the hollow profile 3, the reinforcing element 5, a first ring 13 and a second ring 14 of thermally activated plastic 11. The thermally activated plastic 11 is made of foamed plastic, which completely fills a width of the gap 9, ie a distance between the hollow profile 3 and the reinforcing element 5. In the adhesive cavity 7 adhesive is injected, wherein the adhesive is not shown in Fig. 1. As thermally active plastic 11 is in the present embodiment a permanently elastic foam of ethylene-vinyl acetate or ethylene-butyl acrylate used. But it can also be used other suitable thermally active plastic.
Fig. 2 ist eine schematische Schnittansicht des Hohlprofils 3, in dem das Fig. 2 is a schematic sectional view of the hollow section 3, in which the
Verstärkungselement 5 angeordnet ist. Zwischen dem Hohlprofil 3 und dem Reinforcing element 5 is arranged. Between the hollow section 3 and the

Reinforcing element 7, the annular gap 9 is shown. In the state of FIG. 2, no adhesive or thermally activated or thermally activated plastic is present in the gap 9.
Im Folgenden ist ein Verfahren zum Herstellen des in Fig. 1 gezeigten The following is a method of manufacturing the one shown in FIG
Verbundbauteils 1 gemäß dem ersten Ausführungsbeispiel der vorliegenden Erfindung in Einzelheiten beschrieben. Composite component 1 according to the first embodiment of the present invention described in detail.
Zunächst wird der Klebehohlraum 7 ausgebildet. Hierfür wird thermisch aktiver Kunststoff 11 an geeigneten Stellen auf das Hohlprofil 3 oder/und das First, the adhesive cavity 7 is formed. For this purpose, thermally active plastic 11 at appropriate locations on the hollow section 3 and / or
Verstärkungselement 5 aufgetragen, wie im Folgenden in Bezug auf Figuren 3 und 4 erläutert ist. Reinforcing element 5 applied, as explained below with reference to Figures 3 and 4.
In Figuren 3 und 4 sind Möglichkeiten gezeigt, wo gemäß dem vorliegenden Ausführungsbeispiel der thermisch aktive Kunststoff 11 aufgebracht werden kann. Insbesondere wird, bevor das Verstärkungselement 5 in dem Hohlprofil 3 angeordnet wird, an Orten, an denen eine Begrenzung einer auszubildenden Klebeverbindung ausgebildet werden soll, eine Raupe aus thermisch aktivem Kunststoff 11 aufgetragen. Der thermisch aktive Kunststoff 1 1 wird entweder gemäß Fig. 3 an einer Innenseite des Hohlprofils 3 aufgetragen oder wird in Abwandlung gemäß Fig. 4 an einer Außenseite des Verstärkungselements 5 in Form einer Raupe aufgetragen. Es ist natürlich auch möglich die Raupe oder Teile der Raupe an beiden Hohlprofilelementen aufzutragen. In FIGS. 3 and 4, possibilities are shown where, according to the present exemplary embodiment, the thermally active plastic 11 can be applied. In particular, before the reinforcing element 5 is arranged in the hollow profile 3, a bead of thermally active plastic 11 is applied at locations where a boundary of an adhesive bond to be formed is to be formed. The thermally active plastic 1 1 is either applied as shown in FIG. 3 on an inner side of the hollow profile 3 or is applied in a modification of FIG. 4 on an outer side of the reinforcing element 5 in the form of a bead. Of course, it is also possible to apply the bead or parts of the bead to both hollow profile elements.
Beim Aneinanderfügen des Verstärkungselements 5 und der zwei Hohlprofilbauteile 31 , 33 kann der thermisch aktive Kunststoff 11 bereits eine Vorverbindung zwischen dem Verstärkungselement 5 und den Hohlprofilbauteilen 31 , 33 ausbilden, so dass die Lage des Hohlprofils 3 gegenüber dem Verstärkungselement 5 vorfixiert ist. Alternativ kann die Vorverbindung zwischen dem Hohlprofil 3 und dem When joining the reinforcing element 5 and the two hollow profile components 31, 33, the thermally active plastic 11 may already form a pre-connection between the reinforcing element 5 and the hollow profile components 31, 33, so that the position of the hollow profile 3 is prefixed relative to the reinforcing element 5. Alternatively, the pre-connection between the hollow section 3 and the
Verstärkungselement 5 auch erst nach einem Aktivieren des thermisch aktiven Kunststoffes 11 ausgebildet werden. Reinforcing element 5 are formed only after activation of the thermally active plastic 11.
Nach dem Aufbringen des thermisch aktiven Kunststoffes 11 wird dann das After application of the thermally active plastic 11 is then the
Verstärkungselement 5 z.B. in dem Hohlprofilbauteil 31 angeordnet. Daraufhin wird das Hohlprofilbauteil 33 an das Hohlprofilbauteil 31 gefügt. Nach Bedarf sind geeignete Abstandhalter in Verwendung, die eine Position des Reinforcing element 5 e.g. arranged in the hollow profile component 31. Subsequently, the hollow profile component 33 is joined to the hollow profile component 31. As required, suitable spacers are in use, which are a position of the
Verstärkungselements 5 gegenüber dem Hohlprofil 3, d.h. den Hohlprofilbauteilen 31 und 33, bestimmen. Reinforcing element 5 relative to the hollow profile 3, i. the hollow profile components 31 and 33, determine.
In diesem Zustand ist der Klebehohlraum 7 noch nicht vollständig ausgebildet. Insbesondere verschließt der thermisch aktive Kunststoff 1 1 den Spalt 9 noch nicht vollständig. Es können noch Freiräume vorhanden sein, die den Klebeholraum 7 mit dem übrigen Spalt 9 verbinden. In this state, the adhesive cavity 7 is not yet fully formed. In particular, the thermally active plastic 1 1 does not completely close the gap 9. There may still be free spaces that connect the adhesive space 7 with the remaining gap 9.
Dann durchläuft das so ausgebildete Roh-Verbundbauteil, d.h. das unfertige Verbundbauteil, mit dem Hohlprofil 3, dem Verstärkungselement 5 und dem nicht aktivierten Kunststoff 11 zusammen mit der Kraftfahrzeugkarosserie einen Then, the thus formed raw composite member, i. the unfinished composite component, with the hollow section 3, the reinforcing element 5 and the non-activated plastic 11 together with the motor vehicle body a
Beschichtungsprozess, zum Beispiel einen Tauchlackierprozess. Dabei ist es möglich, dass ein Beschichtungsmittel in den Klebehohlraum 7 vordringt, da der thermisch aktive Kunststoff 1 1 den Spalt 9 noch nicht vollständig schließt. Dies wäre nicht möglich, wenn schon vor dem Tauchlackierprozess eine Klebeverbindung vollständig ausgebildet worden wäre. D.h. das Beschichtungsmittel könnt im Bereich der Klebeverbindung die Elemente des Roh-Verbundbauteils nicht benetzen. Coating process, for example a dip painting process. It is possible that a coating agent penetrates into the adhesive cavity 7, since the thermally active plastic 1 1 does not completely close the gap 9. This would not be possible if an adhesive bond had already been completely formed before the dip-coating process. That The coating agent can not wet the elements of the raw composite component in the area of the adhesive bond.
Um das Beschichtungsmittel auf der Kraftfahrzeugkarosserie und damit auf dem Roh-Verbundbauteil zu Fixieren, durchläuft die Kraftfahrzeugkarosserie mit dem Bauteil einen Trocknungsprozess mit Wärmeeintrag, z.B. einen In order to fix the coating agent on the motor vehicle body and thus on the raw composite component, the motor vehicle body passes through the component to a drying process with heat input, e.g. one
Kathodentauchlackiertrockner (KTL-Trockner). Hierbei wird die Cathodic dip dryers (KTL dryers). Here is the
Kraftfahrzeugkarosserie durch die sowieso für den Trocknungsprozess vorhandene Wärme mit dem Roh-Verbundbauteil soweit erhitzt, dass der thermisch aktive Kunststoff 11 aktiviert wird, aufschäumt und sich damit ausdehnt. Hierdurch wird der Spalt 9 zwischen Hohlprofil 3 und dem Verstärkungselement 5 an den Stellen, an denen der thermisch aktive Kunststoff 11 vorhanden ist, geschlossen. Motor vehicle body heated by the anyway existing for the drying process heat with the raw composite component so far that the thermally active plastic 11 is activated, foams and expands with it. As a result, the gap 9 between the hollow profile 3 and the reinforcing element 5 at the points where the thermally active plastic 11 is present, closed.
Im Falle des in Fig. 1 gezeigten Verbundbauteils 1 ist dann ein Klebehohlraum 7 durch einen ersten Ring 13 und einen zweiten Ring 14 aus thermisch aktiviertem Kunststoff 1 1 sowie die Innenseite des Hohlprofils 3 und die Außenseite des Verstärkungselements 5 ausgebildeter Klebehohlraum 7 gebildet. Weiterhin ist in diesem Zustand das Verstärkungselement 5 bereits verhältnismäßig fest in dem Hohlprofil 3 fixiert. In the case of the composite component 1 shown in FIG. 1, an adhesive cavity 7 is then formed by a first ring 13 and a second ring 14 of thermally activated plastic 11 and the inside of the hollow profile 3 and the outside of the reinforcing element 5 formed adhesive cavity 7. Furthermore, in this state, the reinforcing element 5 is already fixed relatively firmly in the hollow profile 3.
Der Wärmeeintrag in dem Trocknungsprozess des KTL-Trockners ist so hoch, dass eine zu diesem Zeitpunkt schon vorhandene Klebeverbindung den Wärmeeintrag nicht schadlos überstehen würde. Ferner würde beim Vorhandensein einer formschlüssigen Verbindung mittels Bolzen, diese Verbindung durch die The heat input in the drying process of the KTL dryer is so high that an already existing adhesive bond would not survive the heat input without damage. Further, in the presence of a positive connection by means of bolts, this connection would be through the
unterschiedlichen Wärmeausdehnungskoeffizienten des Hohlprofils 3 und des Verstärkungselements 5 eine Überbeanspruchung der formschlüssigen Verbindung stattfinden, die nur mit aufwendigen konstruktiven Maßnahmen zu umgehen wäre. Die Vorfixierung des Verstärkungselements 5 an dem Hohlprofil 3 mittels des thermisch aktivierten Kunststoffs 1 1 , d.h. des aufgeschäumten Kunststoffes mit einer verhältnismäßig hohen Elastizität, ermöglicht jedoch eine relative different coefficients of thermal expansion of the hollow section 3 and the reinforcing element 5 an overuse of the positive connection take place, which would be to be avoided only with elaborate design measures. The prefixing of the reinforcing element 5 to the hollow profile 3 by means of the thermally activated plastic 1 1, i. However, the foamed plastic with a relatively high elasticity, but allows a relative
Verschiebung des Verstärkungselements 5 gegenüber dem Hohlprofil 3 durch deren unterschiedliche Wärmeausdehnung. Displacement of the reinforcing element 5 relative to the hollow profile 3 by their different thermal expansion.
Wenn die Kraftfahrzeugkarosserie mit dem Hohlprofil 3 und dem When the vehicle body with the hollow section 3 and the
Verstärkungselement 5 den Beschichtungsprozess durchlaufen hat, insbesondere wenn die Kraftfahrzeugkarosserie die temperaturintensiven Prozesse durchlaufen hat, kann die eigentliche dauerhafte Klebeverbindung zwischen dem Hohlprofil 3 und dem Verstärkungselement 5 hergestellt werden. Reinforcement element 5 has undergone the coating process, in particular when the motor vehicle body has passed through the temperature-intensive processes, the actual permanent adhesive bond between the hollow section 3 and the reinforcing element 5 can be made.
Wie aus dem oben beschriebenen Verfahren zum Ausbilden des Klebehohlraums 7 ersichtlich ist, muss die Anwendung des thermisch aktiven Kunststoffes so gewählt werden, dass durch einen Ausdehnungsgrad, einen Anwendungsquerschnitt, also im vorliegenden Ausführungsbeispiel der Spalt 9, und einer geometrische Lage der Elemente des Roh-Verbundbauteils, der zu schließende Spalt 9 zwischen dem Hohlprofil 3 und dem Verstärkungselement 5 durch Expansion in dem As can be seen from the above-described method for forming the adhesive cavity 7, the application of the thermally active plastic must be chosen so that by a degree of expansion, an application cross-section, ie in the present embodiment, the gap 9, and a geometric position of the elements of the raw composite component, the gap 9 to be closed between the hollow profile 3 and the reinforcing element 5 by expansion in the
Temperaturprozess des Beschichtungsprozesses geschlossen wird. Der thermisch aktive Kunststoff 1 1 ist ferner so zu wählen, dass er den Temperaturprozess und die dadurch entstehenden Relativbewegungen zwischen dem Verstärkungselement 5 und dem Hohlprofil 3, die aus den Werkstoffen mit den unterschiedlichen Temperature process of the coating process is closed. The thermally active plastic 1 1 is further to be chosen so that it is the temperature process and the resulting relative movements between the reinforcing element 5 and the hollow section 3, which consists of the materials with the different
Wärmeausdehnungskoeffizienten bestehen, unbeschadet überstehen kann. Es kommt also bei der Anwendung des thermisch aktiven Kunststoffes 11 auf die Menge, die Form der Raupe und selbstverständlich auf das Material des thermisch aktiven Kunststoffes 11 an. Thermal expansion coefficients exist unscathed survive. So it comes in the application of the thermally active plastic 11 on the amount, the shape of the bead and of course on the material of the thermally active plastic 11 at.
Zur Herstellung der Klebeverbindung wird dann in den Klebehohlraum 7 ein To produce the adhesive bond is then in the adhesive cavity 7 a
Klebemittel eingespritzt. Da der Klebehohlraum 7 im Wesentlichen durch den ersten Ring 13, den zweiten Ring 14, das Hohlprofil 3 und das Verstärkungselement 5 begrenzt ist, ist der Raum für das Klebemittel auf den Klebehohlraum 7 begrenzt und dringt nicht in andere, nicht dafür vorgesehene Bereiche des Spalts 9 zwischen dem Hohlprofil 3 und dem Verstärkungselement 5 ein. Adhesive injected. Since the adhesive cavity 7 is substantially delimited by the first ring 13, the second ring 14, the hollow profile 3 and the reinforcing element 5, the space for the adhesive is limited to the adhesive cavity 7 and does not penetrate into other unintended areas of the gap 9 between the hollow profile 3 and the reinforcing element 5 a.
Für die Einspritzung des Klebemittels wird entweder eine vor Ausbildung des Klebehohlraums 7 geschaffene Befüllöffnung, z.B. in dem Hohlprofil 3, verwendet oder die Befüllöffnung wird nach Ausbildung des Klebehohlraums 7 durch beispielsweise Bohren eingebracht. For the injection of the adhesive either a filling opening created before the formation of the adhesive cavity 7, e.g. used in the hollow section 3, or the filling opening is introduced after formation of the adhesive cavity 7 by, for example, drilling.
In Fig. 1 ist eine erste Variante des ersten Ausführungsbespiels für eine In Fig. 1 is a first variant of the first exemplary embodiment of a
Klebeverbindung mit einem Klebehohlraum 7 in dem Verbundbauteil 1 gezeigt. Fig. 5 zeigt eine Schnittansicht dieser ersten Variante, wobei der Schnitt durch einen der beiden Ringe 13, 14 verläuft. Adhesive bond with a glue cavity 7 in the composite component 1 shown. Fig. 5 shows a sectional view of this first variant, wherein the section through one of the two rings 13, 14 extends.
Die Klebeverbindung mit dem Klebehohlraum 7 kann jedoch je nach geometrischer Beschaffenheit der Bauteile des Verbundbauteils 1 und den Anforderungen an die Klebeverbindung jeweils angepasst ausgebildet werden. Weitere Varianten hinsichtlich der Klebeverbindung des Verbundbauteils 1 gemäß dem ersten Ausführungsbeispiel sind in Figuren 6 bis 9 gezeigt. However, the adhesive bond with the adhesive cavity 7 can be adapted depending on the geometric condition of the components of the composite component 1 and the requirements of the adhesive bond. Further variants with regard to the adhesive bond of the composite component 1 according to the first exemplary embodiment are shown in FIGS. 6 to 9.
Fig. 6 ist eine schematische Schnittansicht des Verbundbauteils 1 des ersten Ausführungsbeispiels mit einer zweiten Variante des Klebehohlraums 7. Hierbei ist der Klebehohlraum 7 lediglich zwischen dem Hohlprofilbauteil 31 und dem Fig. 6 is a schematic sectional view of the composite component 1 of the first embodiment with a second variant of the adhesive cavity 7. Here, the adhesive cavity 7 is only between the hollow profile member 31 and the
Verstärkungselement 5 ausgebildet. Der Klebehohlraum 7 ist hier also nicht über den gesamten Umfang des ringförmigen Spalts 9 sondern nur als ein Sektor des ringförmigen Spalts 9, insbesondere über eine Hälfte des Umfangs des ringförmigen Spalts 9, ausgebildet. Reinforcing element 5 is formed. The adhesive cavity 7 is thus not formed over the entire circumference of the annular gap 9 but only as a sector of the annular gap 9, in particular over one half of the circumference of the annular gap 9.
Fig. 7 ist eine schematische Schnittansicht des Verbundbauteils 1 des ersten Ausführungsbeispiels mit einer dritten Variante des Klebehohlraums 7. Hierbei ist der Klebehohlraum 7 zwischen dem Hohlprofilbauteil 31 , dem Hohlprofilbauteil 33 und dem Verstärkungselement 5 jedoch nicht über den gesamten Umfang des Spalts 9 sondern über weniger als ein Viertel des Umfangs des Spalts 9, ausgebildet. Ein Sektor des ringförmigen Spalts 9, in dem der Klebehohlraum 7 der dritten Variante ausgebildet ist, erstreckt sich hier über beide Hohlprofilbauteile 31 und 33 jedoch nicht über den gesamten Umfang des Spalts 9. 7 is a schematic sectional view of the composite component 1 of the first exemplary embodiment with a third variant of the adhesive cavity 7. However, the adhesive cavity 7 between the hollow profile component 31, the hollow profile component 33 and the reinforcing element 5 is not over the entire circumference of the gap 9 but over less as a quarter of the circumference of the gap 9, formed. However, a sector of the annular gap 9, in which the adhesive cavity 7 of the third variant is formed, does not extend over both hollow profile components 31 and 33 over the entire circumference of the gap 9.
Fig. 8 ist eine schematische Perspektivansicht des Verbundbauteils 1 gemäß dem ersten Ausführungsbeispiel der vorliegenden Erfindung mit einer Abwandlung der dritten Variante des Klebehohlraums 7. In der Perspektivansicht ist zu erkennen, dass der thermisch aktive Kunststoff 11 eine geschlossene Raupe bildet, die sich abschnittsweise in radialer Richtung und in axialer Richtung des Fig. 8 is a schematic perspective view of the composite component 1 according to the first embodiment of the present invention with a modification of the third variant of the adhesive cavity 7. In the perspective view it can be seen that the thermally active plastic 11 forms a closed bead, which is partially in radial Direction and in the axial direction of the
Verstärkungselements 5 bzw. des ringförmigen Spalts 9 erstreckt, wie das auch in der dritten Variante des ersten Ausführungsbeispiels von Fig. 7 der Fall ist, jedoch in der Schnittansicht nicht zu sehen ist. Im Gegensatz zu der dritten Variante des ersten Ausführungsbeispiels von Fig. 7 ist die geschlossene Raupe des thennisch aktiven Kunststoffes nur zwischen dem Hohlprofilbauteil 31 und dem Reinforcement 5 and the annular gap 9 extends, as is the case in the third variant of the first embodiment of Fig. 7, but in the sectional view is not visible. In contrast to the third variant of the first embodiment of FIG. 7, the closed bead of thennisch active plastic is only between the hollow profile member 31 and the
Verstärkungselement 5 ausgebildet. Reinforcing element 5 is formed.
Fig. 9 ist eine schematische Perspektivansicht des Verbundbauteils 1 gemäß dem ersten Ausführungsbeispiel der vorliegenden Erfindung mit einer vierten Variante des Klebehohlraums 7. In der Perspektivansicht ist zu erkennen, dass der thermisch aktive Kunststoff 11 zwei Ringe 13, 14 ausgebildet hat. Insoweit stimmt die vierte Variante des ersten Ausführungsbeispiels mit der ersten Variante (siehe Fig. 1 ) des ersten Ausführungsbeispiels überein. Der Klebehohlraum 7 der vierten Variante weist zusätzliche Aussparungsabschnitte 15, 16 in dem Klebehohlraum 7 auf. Die Aussparungsabschnitte 15, 16 sind mittels Begrenzungen aus thermisch aktiven Kunststoff 11 derart ausgebildet, dass beim Einspritzen von Klebemittel in den Klebehohlraum 7 die Aussparungsabschnitte 15 nicht mit Klebemittel gefüllt werden. Der Aussparungsabschnitt 15 hat eine ovale Form, während der 9 is a schematic perspective view of the composite component 1 according to the first embodiment of the present invention with a fourth variant of the adhesive cavity 7. In the perspective view it can be seen that the thermally active plastic 11 has two rings 13, 14 formed. In that regard, the fourth variant of the first embodiment is consistent with the first variant (see FIG. 1) of the first embodiment. The adhesive cavity 7 of the fourth variant has additional recess sections 15, 16 in the adhesive cavity 7. The recess portions 15, 16 are formed by means of boundaries of thermally active plastic 11 such that when injecting adhesive into the adhesive cavity 7, the recess portions 15 are not filled with adhesive. The recess portion 15 has an oval shape during the
Aussparungsabschnitt 16 eine eckige Form hat. Jegliche andere Form des Recess portion 16 has an angular shape. Any other form of
Aussparungsabschnitts ist denkbar. Recess section is conceivable.
In dem vorliegenden ersten Ausführungsbeispiel sind das Hohlprofil 3 und das Verstärkungselement 5 rohrförmig ausgeführt.

Selbstverständlich können das Hohlprofil 3 und das Verstärkungselement 5 auch andere Formen und Querschnitte mit im Karosseriebau üblichen komplizierten geometrischen Formen aufweisen. Im In the present first embodiment, the hollow profile 3 and the reinforcing element 5 are tubular. This is merely a simpler explanation of the principle of the invention. Of course, the hollow profile 3 and the reinforcing element 5 may also have other shapes and cross-sections with customary in the bodywork complicated geometric shapes. in the
Übrigen kann das Hohlprofil 3 auch aus nur einem Teil oder aus mehr als zwei Teilen bestehen. Ferner könnte auch das Verstärkungselement 5 aus mehreren Teilen bestehen. Incidentally, the hollow section 3 may consist of only one part or more than two parts. Furthermore, the reinforcing element 5 could consist of several parts.
Insbesondere können gemäß einem zweiten Ausführungsbeispiel der vorliegenden Erfindung, das in Fig. 10 gezeigt ist, auch zwei plattenförmige Bauteilelemente 203 und 205 mit dem erfindungsgemäßen Verfahren zu einem Verbundbauteil 201 miteinander verbunden werden. In particular, according to a second exemplary embodiment of the present invention, which is shown in FIG. 10, two plate-shaped component elements 203 and 205 can also be connected to one another by means of the method according to the invention to form a composite component 201.

Bauteilelement 203 und dem zweiten Bauteilelement 205 ausgebildet ist. Component element 203 and the second component element 205 is formed.
In dem Spalt 209 ist eine Klebehohlraum 207 ausgebildet, der durch die In the gap 209, an adhesive cavity 207 is formed by the
Klebeverbindungsseite des ersten plattenförmigen Bauteilelements 203 und die Klebeverbindungsseite des zweiten plattenförmigen Bauteilelements 205 sowie durch eine Wand aus thermisch aktiviertem Kunststoff 211 begrenzt ist. Die Wand ist in Form eines geschlossenen Rechtecks ausgebildet. Es sind selbstverständlich andere Ausbildungen der Wand möglich. Die Wand erstreckt sich über die gesamte Höhe des Spalts 209 zwischen dem ersten plattenförmigen Bauteilelement 203 und dem zweiten plattenförmigen Bauteilelement 205. Adhesive bonding side of the first plate-shaped component member 203 and the adhesive bonding side of the second plate-shaped member member 205 as well is limited by a wall of thermally activated plastic 211. The wall is in the form of a closed rectangle. Of course, other configurations of the wall are possible. The wall extends over the entire height of the gap 209 between the first plate-shaped component element 203 and the second plate-shaped component element 205.
Der Klebehohlraum 207 ist mit einem Klebemittel gefüllt, das eine dauerhafte Verbindung zwischen dem ersten und dem zweiten Bauteilelement 203 und 205 herstellt. The adhesive cavity 207 is filled with an adhesive that produces a permanent bond between the first and second component members 203 and 205.
Ein Verfahren zum Herstellen des Verbundbauteils 201 gemäß dem zweiten Ausführungsbeispiel funktioniert analog dem Verfahren zum Herstellen des Verbundbauteils 1 des ersten Ausführungsbeispiels, so das es hier nicht weiter erläutert ist. Im Unterschied werden bei dem Verbundbauteil 201 das erste und das zweite Bauteilelement 203 und 205 nicht ineinander sondern aneinander angeordnet und das erste Bauteilelement 203 besteht lediglich aus einem Bauteil und nicht aus zwei Bauteilen wie bei dem ersten Ausführungsbeispiel. A method for producing the composite component 201 according to the second embodiment is analogous to the method for producing the composite component 1 of the first embodiment, so it is not further explained here. In contrast, in the composite member 201, the first and second component members 203 and 205 are not disposed inside each other but against each other, and the first component member 203 consists only of one component and not two components as in the first embodiment.
